To e66 whom it may concem:

- Be it known that I, GEORGE E; GROVER, a citizen cf the Unitezl States and resident of Lynn, in the county of Essex and State of liiessacliusetts, have invented. certain new and useful Improvements in HeeLBuiltling Machines, of which the following is s spec TlllS invention relates to liecl-builcliiig machines and has for its main object to provide an automatic machine by which lii'ts may be assembled to maize a heel blank, coating such lifts with adhesive in the course of so assenibliiig'them; and further to provide as a combined part of such a machine in connection with means for so assembling lifts, a mechanism for receiving the heel blanks made by said means and retaining them under pressure While the aclhesive clries or sets, transferring means for automatically carrying the blanks from'tlie assembling means or mechanism to saitl heel retaining and pressing mechanism, and operating instrumentalities' eirmngeol and organized to efiect conjoint action of said mechanisms and means the proper order. The invention consists in the novel features of the organized machine for carrying cut stated object described in the "following specification, and in the 'principles underlyingtli same, having the characteristics 35 painted out in the appended claims.

The heel-building mechanism ccmprisc means fer applying paste, uncle? which term I include cement, glue, and any other llesive suitable to the purpose tc heel lifts, means for i eeci the lifts into a heel-fun; and nailing mechanism arranged ts drive a lieiltlqi'cugli the lifts while the latter are the form. The heel-pi mechanism compiises series of clamping units each of which is adapted to receive a lieel-blank seal to hold the blank iiiicler pressure until the peste or other adhesive with Whicli the lifts have been coated has liei'cleiiecl. The heel clam )ing units are novcd so 35 to be brought successively into register Witl} the truesfcsring e nism; fifilil cccl umt, iii-tel receiving e iieel-lilzmlt, is closed tc the u; lerpi'essui-e. e may be any desires umbei of llQQL-C unplug units, but I prefer o oi'ovide a. relatively large number so 1 icli heel-Mani; may remain under pressure iciiscgzerel iziiimtes to enable me to set Specification of Letters Fatent.

mastec- The heel-building mechanism includes a feed table pasteapplying means, lift-feeding mechanism, a heel-form in which the lifts are stac zed, nailing mechanism by which a nail is, driven through the lifts which are stacked in the form, and suitable operating mechanismsall of which will be described in due course. Before describing: the structural details, it may be stated that the heel-form includes movable members which are arranged to engage the edges of the lifts and which are reciprocated While the heel-building operation is inprogress, to arrange the lifts in the desired relatipn I01 llfilllng. The operative feeds the lifts manually along the feed table to the feeding; mechanism, and each lift, with the exception of the first lift of each heel, is moved into contact with the paste-applying mechanism before reaching the feed n -v mechanism. \Yhcn the desired number of lifts have been deposited in the heel-form, the operative moves a lever which connects a clutch, and the several mechanisms which are driven while the'said clutch is connected cause the operation of the nail-driving mechanism, the heel-transferring mechanism, the heelcompi'cssiag mechanism, the heel-ejecting mechanism, and \lIhO stop mechanism by which the said clutch is automatically disconnected when one cycle of the trai' sferring operation has been completed.

aft-feeding mechanism.

The feed table is indicated at and shown best by Figs. 7, 8 and 11. The di- :rection of feed is from right to left with 'eference to Figs. 7 and 11. The lifts pass .i om the feed table to a pair of cooperative deed rolls 51 and 52 which, in the present instance, are provided with teeth or spurs. The feed rolls deposit the lifts in the heel.- form, which hereinafterdeseribed. The feed table and feed rolls are moved upward step by step in order to feed the successive lifts of one heel in successively higher planes as the heel increases in height, and then down to the starting point after completion of the heel. For this purpose the feed table and the roll 51 are mounted upon a vertically movable head 53, said head being an ranged to move in guides (See Figs. 3 and 15). The head is sustained by a COlUllmfweight 55 through suitable CODU eEiOBS which include a lever 56 and a link 57. The fulcrum" of the lever is indicated at 58 in Fig. 1. lhe connection between the link 5? and head 53 is'in the form of a knuckle joint, the head being formed With a socket 5.) in which the upper end of the linlt bears. "this form of connection permits angular moven'ient of the link as required by the alig'ulanmvcuu-nt of the lever 56, and the between the feed rolls 51 and 52 forces the upper feed rollupivardly, and this displacement of said upper roll permits of an upward movement of the head as soon as each lift passes beyond the feed rolls, as later more fully described.

The upper feed roll is journaled in a frame 60 which is pivotally connected to the head 53 by pivot members 51. The frame 530. however, is supported by a friction device to. wnich'it is connected by a link 62 and an a i The friction device is shown best by F s. 1 and 15, and includes two cooperative plates ('34 and 65 and an interposed disk 66 of friction material. The arm is affixed to the plate 64, and this plate is arranged to swing about a rod 67. The plate 65 is rigidly connected. to the frame of the machine so that it is not capable of turning. it helical. compression spring 68 is arranged upon the rod 6? and is compressed between the plate 64- and Washers 69 which are held by nuts 70. The force with which the plate 6%- is held against the friction disk by the spring 68 clamps the plate 64: and serves to prevent the head from rising under the lifting stress of the counterweight When thereis no lift between the feed rolls 51, 52, the upward stress of the head 53 is sustained by an abntment Tl (Fig. 10), which bears against the pivoted frame (30; but whenever a lift enters between the rolls, rolls are forced apart by the lift, and the lift takes the place of the abutment Tl in sustaining the up ward stress of he head The separation of the roll 51' and 52 by the is sudden and re ts in upward movement of roll rather downward movement of roll 51, because the inertia ofthe head 53, counterweight 55, and their connections, is

substantially greater than that of the ele-- ments which would be moved by upward movement of roll 52. Consequently, whenever a lift enters between the rolls, the friction plate 6i is turned slightly with relation to the plate 65, and soon'as the lift passes from the feed rolls the head 53 rises until it is arrested by the abutment 71. he head and feed rolls are thus raised step by step as the lifts are fed, until the desired number of lifts have been deposited in the heel-form.

' The head is automatically returned to its lowered position preparatory to feeding the fir t lift of each heel. For this. purpose the friction plate 6-! is provided with an
